Problems solved by technology

A clinician can not always accurately measure an anatomical feature using a paper measuring tape, and manipulating the tape along the patient's body to obtain a measurement is often an awkward and time-consuming chore.

Embodiment Construction

[0014]According to exemplary embodiments of the present invention, a measuring device is used to determine the appropriate length of a medical device required to perform a medical procedure. For example, the measuring device may be used to estimate the length of a catheter required to reach from an insertion site to a target site within the patient's body. According to an exemplary method of the invention, a measuring device is used to estimate the distance from a catheter insertion site to a target site by running the measuring device along and external to the body of the patient to follow a presumed path from the insertion site to the target site. The catheter may then be appropriately trimmed according to the estimated distance obtained by the measuring device. Although a measuring device that uses a rotating measuring wheel is described herein, it should be appreciated that any suitable automatic measuring device may be used in the present inventive method. Further, the measurin...

Abstract

A method of inserting a catheter into a body of a patient includes identifying a catheter insertion site on the patient's body; measuring a length, from the insertion site to another site external to the body of the patient, and along an external path that follows a presumed internal path of the catheter from the insertion site to a target site within the patient's body, using an automatic measuring device; trimming the catheter to an appropriate length based on the length measured by the automatic measuring device; and inserting the trimmed catheter into the body of the patient through the insertion site to the target site.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method of measuring the appropriate length of a medical device to be inserted into the body of a patient, and more particularly to a method for measuring a portion of a patient's body to determine the appropriate length of a catheter to perform a medical procedure.BACKGROUND OF THE INVENTION[0002]Proper tip placement for a catheter within the body of a patient is usually achieved by measuring some external anatomical feature and choosing and / or trimming the catheter to be placed to the proper length based on this anatomical measurement. Typically, a paper measuring tape is included in the procedure tray along with all of the other disposable equipment utilized in placing a catheter. This measuring tape is used to measure the desired anatomical feature to determine the appropriate length of the catheter to be inserted.[0003]A clinician can not always accurately measure an anatomical feature using a paper measuring tape, a...
